Virtual Primary Reference Time Clock
The virtual Primary Reference Time Clock is an innovative architecture that delivers precise timing for data centers with reduced reliance on Global Navigation Satellite System (GNSS)-based timing signals.
Timing Solutions
Regulatory and user requirements for data centers demand sub-microsecond sequential time stamps. Time stamping precision and accuracy is critical not only across servers in a data center, but also between data centers in a network. From hyperscale applications to colocation data center clients, we offer a full range of timing solutions, including the Virtual Primary Reference Clock (vPRTC), that ensure precise, accurate, secure and resilient time.

Virtual Primary Reference Time Clock (vPRTC)
The requirements for timing and synchronization are shifting from accuracy and precision to security and resiliency. Simply delivering an accurate timing instance is no longer enough. Designers of critical infrastructure must ensure that their timing source can be validated and trusted, that they maintain network-wide visibility and monitoring and, most importantly, that they have resiliency in the form of backups and protection when something goes wrong, because it will.
